We highly recommend insuring your belongings while they are in storage. Although we go to great lengths to ensure the safety of your belongings, there are circumstances that are beyond our control that could result in harm to your belongings. Your homeowners' or business insurance policy may cover items stored outside your home or place of work, but most won't cover flood damage. Consider purchasing a personal articles policy for valuables and larger ticket items.
Keep a list of EVERYTHING you have stored in your unit, and remember to update that list each time you put more items into storage or take anything out.
